add: test for allowed duplicate choices with translations

- prior to always generating secondary instances, this scenario would
  have not output the duplicate choices, even if allowed. Now, itext
  are identified by choice position so it's not a problem. This test
  adds to the existing suite by using translations with the duplicates.
